访问 Android 的存储时出错：java.net.MalformedURLException：无协议：

Question

我在尝试访问应用程序的存储空间时遇到此错误（尝试了私有和共享）。我尝试添加 file:// 但它似乎没有帮助。

            String path = getFilesDir().getAbsolutePath() + File.separator + BUNDLE_NAME; // /data/user/0/com.package.vpn/files/rn.bundle
            File file2 = new File(path);

            if (file2 != null && file2.exists()) {
                try {

                    mReactInstanceManager = ReactInstanceManager.builder()
                            .setApplication(getApplication())
                            .setCurrentActivity(currentActivity)
                            .setJSBundleFile(path) // accessing internal storage
                            .addPackages(packages)
                            .setUseDeveloperSupport(BuildConfig.DEBUG)
                            .setInitialLifecycleState(LifecycleState.RESUMED)
                            .build();
                } catch (Exception e2) { }

错误：

文件确实按预期加载（没有添加 'file://'），但错误不断发生。

您缺少 setJSMainModulePath("index")
